[0037] Specifically, in combination Figure 1 and Figure 2 As shown, the base 110 has a first groove 111. The connecting plate 120 has a welding joint 121 and a protrusion 122. The protrusion 122 is located on one side of the connecting plate 120 and is positioned at the welding joint 121. The fixing member 130 is located on the side of the connecting plate 120 opposite to the base 110. When in the first assembly position, the first groove 111 is used to position the cover plate 230, the connecting plate 120 is positioned facing the first groove 111, the welding port 121 corresponds to the battery connecting piece 240, and the protrusion 122 is used to abut against the battery connecting piece 240.

The battery tab 220 connected to the battery cell 210 is positioned facing the first groove 111. After the battery tab 220 and the battery connecting piece 240 are welded, the cover plate 230 is placed in the first groove 111 to facilitate the positioning of the cover plate 230. The cover plate 230 is welded to the battery tab 220 and the battery connecting piece 240 through the welding port 121. That is, the welding of the cover plate 230 is achieved in the first assembly position of the welding fixture 100.

[0039] For example, the connecting plate 120 is made of metal, such as copper, so that it has a high melting point and good heat dissipation performance, so as to dissipate the heat generated during welding.

[0045] In summary, the welding fixture 100 has at least a first assembly position. When the welding fixture 100 is in the first assembly position, the cover plate 230 is installed in the first groove 111 of the base 110. At this time, the battery tab 220 and the battery connecting piece 240 are placed in the corresponding positions of the cover plate 230.

Correspondingly, when the welding fixture 100 is in the first assembly position, the cover plate 230 is installed in the first groove 111 of the base 110. At this time, the battery tab 220 and the battery connecting piece 240 are placed in the corresponding positions of the cover plate 230, and the cover plate 230 and the battery tab 220 are limited and fixed by the connecting plate 120. The protrusion 122 of the connecting plate 120 can abut against and limit the battery connecting piece 240. The fastener 130 installs and fixes the connecting plate 120 and the base 110. The welding joint 121 corresponds to the position of the battery connecting piece 240, so as to clamp and fix the cover plate 230 and the battery tab 220, reduce the possibility of the battery connecting piece 240 shifting or misaligning during welding, so that the battery connecting piece 240 and the cover plate 230 can be welded through the welding joint 121 at the first assembly position, thereby improving the accuracy and precision of welding and thus improving the welding effect.

[0050] refer to Figures 1 to 3 As shown, the welding fixture 100 has a first direction X, a second direction Y, and a third direction Z, wherein the first direction X, the second direction Y, and the third direction Z are arranged perpendicularly to each other. For example, the first direction X is the width direction of the welding fixture 100, the second direction Y is the length direction of the welding fixture 100, and the third direction Z is the height direction of the welding fixture 100.

[0051] In one embodiment, alternatively, such as Figure 1 As shown, there are two fasteners 130. The two fasteners 130 are arranged side by side along the first direction X, that is, along the width direction of the welding fixture 100. This is to facilitate the connection and fixation of the base 110 and the connecting plate 120 through the fasteners 130, to prevent the connecting plate 120 from shifting or moving during the welding process, and to improve the clamping effect when welding the battery tab 220.

[0052] Optionally, refer to Figure 4 and Figure 5As shown, the base 110 is provided with a first mounting hole 112, and the connecting plate 120 is provided with a second mounting hole 123. The fixing member 130 passes through the second mounting hole 123 and the first mounting hole 112 in sequence. Correspondingly, the first mounting hole 112 is provided corresponding to the second mounting hole 123. The fixing member 130 can pass through the second mounting hole 123 and the first mounting hole 112 to connect the connecting plate 120 and the base 110. Further, the fixing member 130 is a fixing bolt. The fixing bolt can pass through the second mounting hole 123 and the first mounting hole 112 and be bolted to the wall of the first mounting hole 112 of the base 110 to fix and fasten the connecting plate 120 and the base 110.

[0053] Optionally, combined Figure 1 and Figure 2 As shown, the protrusion 122 extends toward the side away from the connecting plate 120 relative to the welding port 121, that is, the protrusion 122 has a protruding portion relative to the connecting plate 120, and the protrusion 122 is located at the welding port 121. At this time, the battery connecting piece 240 is located between the base 110 and the connecting plate 120, so that the protrusion 122 abuts against and limits the battery connecting piece 240, so that the battery connecting piece 240 can be welded through the welding port 121, keeping the position of the battery connecting piece 240 still, and having a better welding limiting effect.

[0054] In one embodiment, alternatively, referencing Figure 3 and Figure 4As shown, the welding fixture 100 also includes a positioning plate 140, and the welding fixture 100 also has a second assembly position. When in the second assembly position, the positioning plate 140 is disposed in the first groove 111, and the positioning plate 140 is engaged with the groove wall of the first groove 111.

The side of the connecting plate 120 away from the protrusion 122 is disposed towards the positioning plate 140 to avoid the protrusion 122 affecting the clamping and fixing between the connecting plate 120 and the positioning plate 140. The connecting plate 120, the positioning plate 140, and the base 110 are movably connected by the fixing member 130. In other words, the welding fixture 100 can also be in the second assembly position. In this position, the positioning plate 140 is installed in the first groove 111, causing the battery connecting piece 240 and the battery tab 220 to abut against the positioning plate 140 and the connecting plate 120. The connecting plate 120 abuts against the positioning plate 140, and the battery connecting piece 240 and the battery tab 220 are welded through the welding port 121 of the connecting plate 120. This allows the welding fixture 100 to position and clamp the battery connecting piece 240 and the battery tab 220 in the second assembly position, improving the processing method of the welding fixture 100. For example, the shape and dimensions of the positioning plate 140 match the dimensions of the first groove 111.

[0055] Optionally, such as Figure 4 As shown, the positioning plate 140 is provided with a third mounting hole 141. The fixing member 130 passes through the third mounting hole 141, the second mounting hole 123, and the first mounting hole 112.

The fixing member 130 can pass through the third mounting hole 141, the second mounting hole 123, and the first mounting hole 112 to facilitate the fixed connection of the positioning plate 140, the connecting plate 120, and the base 110. At this time, the positioning plate 140 abuts between the connecting plate 120 and the base 110. Further, the base 110, the positioning plate 140, and the connecting plate 120 are arranged sequentially along the third direction Z.

[0056] Optionally, the positioning plate 140 has a second groove 142 on the side opposite to the base 110. The second groove 142 is used to position the battery connecting piece 240. The second groove 142 of the positioning plate 140 facilitates the positioning of the battery connecting piece 240, reducing the possibility of the battery connecting piece 240 shifting during the welding process, thus achieving better technical results. For example, there are multiple second grooves 142, with one second groove 142 corresponding to one battery connecting piece 240.

[0057] In one embodiment, alternatively, referencing Figure 3 and Figure 4 As shown, the welding fixture 100 also includes a limiting member 150. The base 110 is provided with a sliding groove 113, and the limiting member 150 is provided with a slider. The limiting member 150 is slidably connected to the sliding groove 113 via the slider. Correspondingly, the limiting member 150 can slide within the sliding groove 113 via the slider. The limiting member 150 plays a role in limiting and fixing the battery cell 210, preventing the battery cell 210 from moving or shifting, and improving the clamping and fixing effect during welding. Furthermore, there are multiple limiting members 150, and multiple limiting members 150 work together to limit and fix the battery cell 210.

[0058] Optionally, such as Figure 4 and Figure 5 As shown, the slide 113 includes a first slide 1131 and a second slide 1132. The first slide 1131 is arranged along a first direction X, and the second slide 1132 is arranged along a second direction Y. The second direction Y is perpendicular to the first direction X. In other words, the first slide 1131 is arranged along the width direction of the welding fixture 100, and the second slide 1132 is arranged along the length direction of the welding fixture 100. After the battery cell 210 is placed on the base 110, the limiting member 150 is moved along the positions of the first slide 1131 and the second slide 1132 respectively, so that the limiting member 150 abuts against the battery cell 210, thereby limiting and fixing the battery cell 210. For example, the limiting member 150 is a limiting plate, and a slider is provided at one end of the limiting plate.
